NASA’s innovative DAWN spacecraft studied the conditions and processes of the solar system’s earliest epoch by investigating in detail two of the largest protoplanets in the Asteroid Belt still remaining intact since their formations: the giant asteroid Vesta and dwarf planet Ceres, two main asteroid belt worlds that followed very different evolutionary paths. Using exceptionally efficient electric ion propulsion, DAWN became the first and only spacecraft to orbit two different deep space bodies on the same mission! Come see incredible photos of these two worlds, what it took to get there, and what we’ve learned!
